CLOSURE-OPERATING MEANS.

Application filed September 24, 1921.

To all whom it may concern.

Be it known that I, HENRY E. BRUMMEL, a citizen of the United States,residing at Boonville, in the county of Cooper and State of Missouri,have invented certain new and useful Improvements in Closure-OperatingMeans, of which the following is a speci fication, reference being hadto the accompanying drawings.

This invention relates to closure operating means, and has for itsobject to provide means of this character adapted for connection to adoor or gate to permit opening and closing of the door or gate atdistance.

It is another object of the invention to provide means of this characterincluding a novel actuating member which when operated causes closingand opening of the closure member, said member being movable vertically.

It is also an object of the invention, to provide means of thischaracter for actuating a double closure member, such as two doors,means being connected to one door for actuation by an operator, andmeans connected to said door and to the remaining door for operating theremaining door upon movement of the first mentioned means.

It is still'a further object of the invention to provide a device ofthis character inelud ing a foldable actuating member which when thedoor or closure member is opened is disposed in its extended position,and when the door is closed, in its folded position, said member beingalso connected to means for operating the latches of the closure memberand adapted toprevent aecidental closing of the door or closure member.

WVith these and other objects in view, the invention consists in theimproved construction and arrangement of parts to be hereinafter moreparticularly described, fully claimed and illustrated in theaccompanying drawings, in which Figure 1 is a view in elevation of thepair of closure members closed showing the position of the actuatingmember;

Figure 2 is a top plan view of the doors in their open positions;

Figure 3 is a perspective view of one of the actuating members;

Figure 4 is a perspective view of the main actuating member;

Serial No. 502,909.

Figure 5 is a view in elevation of the structure shown in Figure 2;

F lgure 6 is an interior elevation of the closure members showing thearrangement of the latches;

Figure 7 is a side elevation of one of the closure members in its openposition; and

Figure 8 is a fragmentary sectional view showing the connection of themain actuating member to the closure member and latches.

It is of course obvious that this mechanlsm can be applied to all formsof closure members, including a gate or door. For the purpose ofillustration, doors are used. In this embodiment of the invention, 5 and6 designate the walls of a building, and 7 and 8 the closure members ordoors. These doors are the type used on garages, warehouses, and forclosing large door ways. The doors are hinged to the wall in the usualmanner. The door 8 is provided with a relatively large opening or slot9, While secured to the inner surface of the door 8 adjacent the slot 9is a bearing block 10 from which a pin 11 projects, the purpose of whichwill be hereinafter described.

To open and close the door 8, a novel actuating member 12 is provided,said member comprising a pair of strips 13 and 14 which are hinged atone of their ends to each other. Hingedly connected to the strip 18 atits opposite end is a plate 15, while hingedly connected to the oppositeend of the strip 1 1- isia plate 16, the plate 15 having an opening 17,while the plate 16 is provided with a slot 18. Projecting from the strip14- adjacent the connection of the strips to each other is an eye member19, the purpose of which will be hereinafter described.

Positioned adjacent the hinged connection of the closure member or door8 to the wall 6 and in spaced relation to the wall of the building is astandard 20 which may be secured in any suitable manner, while extendingfrom the standard 20 and con-, neeted to the wall 6 is a supportingmember 21. Projecting from the top of the stand ard 20 is a bar 22 fromwhich pulleys 23 and 24 depend.

The plate 15 of the actuating or hinge member '12 is pivotally connectedto the standard 20 by means of a pin extending through the opening 17,the actuating memof their ends to each other.

end of the strip 40 is reduced and threaded her being connected to thesupport 21 adjacent the standard 20. lt will be noted that thesupporting member 21 is disposed below the slot 9 so as to prevent theactuating member from being disposed on a dead center. The plate .16 isadapted to extend through the slot 9 the pin 11 being passed through theslot 18 of the plate 16, the plate 16 being prevented from disengagementby means of a fastening pin passed through the pin 11. As shown inFigure 1 the strips 13 and 14- aredisposed in angular re lation to eachother so that the actuating n'iember will readily respond when it isdesired to open the doors or closure members. Projecting from the end ofthe plate 16 is an eye 26 to which a wire or cable 27 is connected.Pivoted to the inner face of the door 8 adjacent the slot 9 is a bellcrank lever 28 to the end 29 of which the cable 27 is connected.Extending from the ends 29 and 30 of the bell crank lever are cables 31and 32, the cable 31. being connected to the intermediate portion o? alatch member 33 which is pivoted to the upperportion of the door 8 as atill, while lhecable 32 is pivotally connected to the intermediateportionof a latch member 35 which is likewise pivotally connected to the lowerportion of the door as at 36. To hold the doors 7 and Sin their closedpositions, a pair of substantially Z-shaped keepers 37 and 38 areprovided, the keeper 3? having its bill disposed downwardly so that uponupward movement of the latch member 33 the end of the latch will bedisposed within the keeper. The keeper 38 has its bill disposed upwardlyso that upon downward movement of the latch member 35 the end of thelatch will be received by the keeper. Qperation of the latches isaccomplished simultaneously.

In order to permit both closure members or doors 7 and 8 to be openedsimultaneously there is provided an auxiliary actu ating' member 39comprising a pair of strips 40 and 41, said strips being hinged at oneThe opposite to 'providea stem adapted to extend through an'openingprovided inthe upper corner portion of the door 8. Nuts 42 and as areused to hold the strip 410 rigid.

Pivot'ed to the opposite end of the strip 41 is a plate 1 1 which isadapted to be secured to the upper corner portion of the door A brace 45is connected at one end of'the door 8 and at its opposite end to thestrip 40 so as to maintain the strip 10 substantially at'right angles-tothe door 8 at all times and to prevent independent move- I ment of saidstrip. The strip 41, however,

intended to oscillate. The strips 40 and 411 are of a lengthsutficientto prevent the central pivotal connection of the actuating member 39from being disposed on a dead center so that there is a slight bulge inthe actuating member 39 when the doors 7 and 8 are disposed at the limitof their open movement as shown in Figure 2.

When the doors are in their closed positions, as shown in Figures 2 and6, the strips 13 and 14 of the actuating member 12 are disposed inangular relation, while the strips i0 and all of the actuating member 30are disposed substantially parallel to each other. or other words,ltshaped.

Connected to the eye member 19 is ring 45 to which a pair of cables asand 47 are connected. These cables extend over the pulleys and 2 1-. Thecable 1'? extends through the wall (5 to the exterior of the buildingwhile the cable l6 extends inwardly of the building. l l hen either ofthe cables 16 or l? is pulled, the strips 13 and 1e are movedsubstantially upwardly, the strip 13 at the same time moving toward thestandard 20, while the strip 1 1 is moving in a horizontal position.

This also causes sliding increment of the plate 15 on the block 10,which movement causes the cable or wire 27*to oscillate the bell cranklever 28 thereby moving the latch members 33 and 34 toward each otherand disengaging the same from the keepers 3i and 38 whereby the doorsare unlatched. Continued pull on the cable will cause the strip l t tomove toward and beyond the standard 20. at thesame time, the plates 15and 16 are swung on their respective supports so as to position theactuating member 12 at right angles to the door. In this way the strip13 is gradually moved beneath the strip 1 1 to fold the actuating member12 as shown in Figures 2, 5 and 7.

As soon as the doors 7 and 8 start to move the strip 40 of the actuatingmember 39 moves with the door 8 it is rigidly connected. This causespivotal movement of the strip 4-]. thereby moving the door 7 similar tothe door 8.

' To close the doors 7 and 8 the desired cable is again pulled so as toraise the strips 13 and 14: to the position shown in Figure 5 and inview of the fact that the pulleys 23 and 24 are disposed inwardly oi:the connection of the strips 13 and let to each other, said strips willbe moved toward and beyond the standard 20 thereby causing the door 8 toswing away from the standard 20. Continued pull upon the cable willcause the connect-ion of the strips 13 and 1a to pass beyond the centerof gravity and then through the medium of gravity swing the door 8 toits closed position, whereupon the strips of the actuating member-l2will be moving the door 7 to its closed position. T he closing movementof the actuating member 12 causes sliding movement 01"? the plate 16 onthe block 10 thereby oscillating the bell crank lever :28 and permittingthe latch members 33 and to engage their respective keepers.

From the foregoing it will be readily seen that this invention proridesa novel and simple closure operating mechanism that is capable of beingoperated by anyone. In addition to this the novel position of the strips13 and ii of the actuating member 12 prevents accidental closing or, thedoors when in their open positions thereby eliminating the necessity ofseparate props. Furthermore, both of the cables may be used for openingand closing the doors and both doors are swung to their open and closedpositions by a slight pull on one of the cables.

What is claimed is 1. In combination with a closure member having anopening therethrough, a bracket carried by said closure adjacent theopening, latch means carried by the closure member, a hinge membercomprising a pair of strips hinged at one of their ends to each other, aplate hinged to each of the opposite ends of the strips, one of saidplates being slidably mounted on the bracket and movable through saidopening and operatively connected to the latch means, the remainingLin!) plate being pivoted to a support adjacent the closure member andadapted to oscillate on the support upon folding movement of the stripsrelative to each other, and actuating means connected to one of saidstrips closely adjacent the hinged connection oi? the strips to eachother.

2. In combination With a closure member having an opening therethrough,bracket carried by said closure adjacent the opening, latch meanscarried by the closure men'iber, a hinge member comprising a pair ofstrips hinged at one of their ends to each other, a plate hinged to eachof the opposite ends 073? the strips, one of said plates beingSlitlibljf mounted on the bracket and movable through said opening andoperatively connected to the latch means the remaining plate beingpivoted to asupport adjacent the closure member, the strip of the hingemember to Which the last mentioned plate is connected being normallydisposed in angular relation to the remaining strip of the hinge member,said remaining strip being normally disposed substantially in ali nmentWith the plate mounted on the bracket, and actuating means connected tothe last mentioned strip for folding said strips one upon the other andupon the plate pivoted to the support.

In testimony whereof I hereunto affix my signature.
